Low temperature sintering of highly dense SiC ceramics is one of the research focuses of scholars in industries, because of the high degree of Si-C covalent bonding and the low self-diffusion coefficient of SiC. Noting that low-temperature eutectic liquid phase transition between Pr3Si2C2 and SiC can promote the sintering of SiC, Pr3Si2C2 was grown in-situ on the surface of SiC particles by using a molten salt method, in order to ensure the uniform dispersion of Pr3Si2C2 in the SiC particles. SiC ceramics with high density (porosity of 0.3%) and thermal conductivity of up to 106 W·m-1·K-1 were successfully fabricated, by using electric current field-assisted sintering technology at a low temperature of 1500 ℃. According to microstructure of the SiC ceramics, it is concluded that the sintering process followed a typical solution-precipitated liquid phase sintering mechanism. Therefore, Pr3Si2C2 is a promising low-temperature sintering additive for the low-temperature sintering of SiC ceramics and their composites.
